Discussion of 'Field Investigation of Soil Heave by a Large Diameter Chilled Gas Pipeline Experiment, Fairbanks, Alaska' by Scott L. Huang, Matthew T. Bray, Satoshi Akagawa, and Masami Fukuda

摘要

The authors present the result of a full-scale testing program to measure pipe movements due to frost heave along the test pipeline. The purpose of this discussion is to provide additional information and to clarify some aspects of the testing program, and in some limited cases, to challenge the hypotheses proposed by the authors. The discussers have special knowledge of the testing program described in the paper. The first discusser was the technical manager for the initial investigations and installation of the pipeline test section and most of the instrumentation. The repair and recommissioning of the mechanical equipment and installation of the pipeline test section was carried out by AMEC Earth & Environmental under contract to the Japanese Science and Technology Corporation (JST). In addition, Foothills Pipelines Limited provided both financial and technical support during the commissioning and construction phases. The authors assumed responsibility for the testing results shortly after the program began.
